Turner, who won the prize two years ago with the Arctic Monkeys, appears in the 12-strong shortlist announced today for his side project with Miles Kane. Other young stars on the list include Estelle, Adele and Laura Marling. Wild cards in a traditionally eclectic selection include Portico Quartet, a modern jazz group from London who used to busk outside the National Theatre, dubstep musician Burial and folk act Rachel Unthank And The Winterset, featuring Geordie sisters Rachel, 29, and Becky, 22.
